Remove Thoth from minimal template

[isaacabraham]

I think we should remove Thoth from the minimal template - or at least from the code sample (maybe just keep as a package reference?) - it's simply not required. We also no longer need the use the json combinator on the back end:

On the server

let webApp = router {
    get Route.hello (text "Hello from SAFE!")
}

On the client

...
let! response = Fetch.fetch Route.hello [] // Uses the built-in browser Fetch API that comes with Fable.
let! message = response.text()
header.innerText <- message
...

I was wrong. That Fetch method is supplied by the Thoth package. But we don't need to include the Thoth-specific members in the code. In other words, I think that the sample above should still be used - it only uses the raw fetch method which is standard in Browsers rather than the Thoth-specific extensions.

#415 doesn't contain Thoth on Server side anymore in minimal template. AFAIK for Fetch API inside fable you either need to use Thoth.Fetch or Fable.Fetch package. I'll see if I can make #415 use the latter one

Awesome. Could / should we use text rather than json (given that the message is actually just plain text)?
